Apache Jena Training in Copenhagen, Denmark

This course introduces participants to Apache Jena, a popular open-source Java framework for building Semantic Web and Linked Data applications. The training covers RDF data modeling, ontology handling, SPARQL querying, and using Jena APIs to store, query, and integrate semantic data. Participants will also gain hands-on experience with Jena TDB and Fuseki for persistent storage and SPARQL endpoints.
